Overview

Stock Options is an onchain options market for tokenized stocks — AAPL, NVDA, TSLA, META, AMZN and others. Holding a tokenized stock gives you exposure to its price. An option gives you exposure to what that price does next: a defined view on direction, distance and time.

Stocks let you trade the price. Options let you trade what happens next.

The contract

Every market is described by four fields, and reads as a single line:

NVDA $200 Call — Sep 25

FieldMeaning
UnderlyingThe tokenized stock or index the contract references.
DirectionCall for upside, put for downside.
StrikeThe price level the contract is measured against.
ExpiryThe date the contract settles.

One contract references 100 units of the underlying, matching the convention of the market it tracks.

Four choices

The interface is deliberately shorter than a traditional options ticket. There are four decisions and no others:

  • Pick a stock. The underlying you have a view on.
  • Pick a direction. Call or put.
  • Pick a target. The strike — the level you want exposure from.
  • Pick an expiry. 1D, 1W, 1M and longer-dated markets.

Everything else — premium, break-even, delta, collateral — is derived from those four choices and shown before you sign anything.

Buying options

You pay the premium up front. That premium is your maximum loss: if the contract expires without value, nothing further is owed and nothing further can be taken.

Calls

A call gains intrinsic value when the underlying settles above the strike. Break-even is the strike plus the premium paid.

Puts

A put gains intrinsic value when the underlying settles below the strike. Break-even is the strike minus the premium paid.

Between now and expiry, a contract also carries time value, which decays as expiry approaches. Short-dated markets decay fastest.

Writing options

The other side of the book is open. Writing — selling — an option collects the premium immediately in exchange for taking on the obligation at expiry.

  • Written positions are backed by collateral locked for the life of the contract.
  • If the contract expires worthless, the writer keeps the premium and the collateral unlocks.
  • If it expires in the money, settlement is taken from the collateral automatically.

Selling premium carries risk that is larger than the premium collected. The terminal shows the collateral requirement before the position is opened.

Exercise & settlement

Contracts settle onchain against the price of the underlying tokenized stock or index at expiry. There is no broker, no assignment queue and no manual exercise window to miss — an in-the-money contract settles to its intrinsic value and an out-of-the-money contract settles to zero.

Because settlement is written into the contract rather than negotiated afterwards, the payoff you saw when you opened the position is the payoff you get.

Network

Stock Options runs on Robinhood Chain mainnet only. The site will ask your wallet to switch networks, and to add the network if it is not present.

Wallet

Connect any EIP-1193 wallet through the connect button in the header. Wallets are discovered with EIP-6963, so every installed wallet appears rather than only the one that claimed the injection slot.

  • The session is remembered and reconnects silently on your next visit.
  • Account and network changes are picked up live, without a reload.
  • Wallet settings — address, network, balance, explorer link and disconnect — live behind the same button once connected.

Orders are only accepted on Robinhood Chain. If your wallet is on another network, the terminal will prompt you to switch before an order can be signed.

Risk

Options can expire worthless. Buyers can lose the entire premium paid; writers can lose more than the premium collected. Short-dated contracts are the most sensitive to both time and volatility.

Nothing here is investment advice.
